HOLDING MEANS FOR SPINNING AND TWISTING RINGS.

Application filed. July 20, 1909.

To all whom it may concern:

Be it known that I, ALBERT C. RHODES, a citizen of the United States, and resident of Hopedale, county of lVorcester, State of Massachusetts, have invented an Improvement in Holding Heans for Spinning and Twisting Rings, of which the following description, in connect-ion with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

In the use of spinning or twisting apparatus it is customary to change the rings on the frame to correspond to the count of the yarn, large rings being required for some counts and small rings for other counts. Various means have been devised for facilitating the change of the rings, involving in some cases sets of plates adapted to be mounted interchangeably on the ring-rail and arranged to hold rings of different diameters, and in other cases adjustable holders have been proposed.

My present invention has for its object the production of simple, novel and efficient means for holding in place the rings of spinning or twisting apparatus, the construction and arrangement being such that the change from rings of one size to those of another size can be made easily and quickly.

In accordance with my invention the spindle opening in the ring-rail is annularly recessed or counterbored to fit the flange of the largest ring to be used, the ring being held in place by means of a resilient member integral with the ring-rail and forming a part of the ring seat. This resilient member is set up by means of a clamping screw mounted in the rail and cooperating with said member. When smaller rings are to be used they are fitted into sheet-metal holders having an outside diameter equal to that of the flange of the largest ring. By setting back the clamping screw the change from one size of ring to another is very easily effected.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure l is a top plan view of a portion of a ring-rail and a ring, embodying one form of my invention, the largest size ring being shown held in place; Fig. 2 is a transverse section thereof on the line 22 Fig. 1; Fig.

Specification of Letters Patent.

Serial No. 508,611.

3 is a view similar to Fig. 1 but showing a smaller ring and its holder, the latter being clamped into the ring-rail; Fig. 4 is a transverse sectional view on the line et t, Fig. 3.

In the drawings 1 represents a portion of the ring-rail provided with a spindle opening 2, and in accordance with my present invention this opening is annularly recessed or counterbored to form an annular seat 3 which fits the flange 1' of the largest ring R to be used, the ring shown being of the well-known double-flanged type.

A portion of the web of the ring-rail forming the wall of the spindle opening is made resilient or slightly yielding, to constitute a holding member, and herein I have shown the web slotted or cut through at at, 5 to leave a segmental portion 6 which forms the resilient holding member.

A clamping screw 7 seated in a threaded hole 8 in the front of the rail crosses the curved part 5 of the slot and bears against the member 6 near its free end.

The flange I of the largest ring to be used is seated in the annular seat 3 and then the screw 7 is set up enough to press the holding member 6 firmly against the adjacent portion of the ring flange, thereby securely clamping the ring in position.

It will be noted that the annular seat 3 is formed in part in the resilient or adjustable holding member 6, and the construction described is clearly illustrated in Figs. 1 and 2.

When it is desired to use smaller rings, as R Figs. 3 and 4, I provide a preferably sheet-metal ring-plate or carrier 9 having ears 01' lugs 10 to embrace the lower flange of the ring, such ring-plate or carrier having a circular edge 11 which is of the same diameter as the flange 1 of the largest ring R.

The ring having been applied to the ringplate or carrier the latter is seated in the seat 3 and held in place by the action of the member 6 when the screw 7 is set up.

If desired several sets of ring-plates or v carriers may be provided, all having the same outslde diameter, but the different sets will be arranged to hold rings of different ings, and it will be seen that the change from rings of one size to rings of another size can be effected easily and quickly.

The means for holding the rings in place on the ring-rail is very simple and effective, and as there are no parts projecting above the rail there is little opportunity for lodgment of lint or dirt thereon.

So far as my invention is concerned the ring-plates or carriers may be made in any suitable way to engage the ring, provided that the outside edge or periphery thereof is of the same diameter as the flange of the largest ring tobe used.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A ring-rail provided with a spindle opening and having a concentric annular seat adapted to receive the flange of a ring, or a ring-carrier, a resilient holding member integral with the ring-rail and in which a portion of the annular seat is formed, and means to press said holding member inward.

2 In ring spinning or twisting apparatus, a ring-rail provided with a spindle opening and having a concentric annular seat for the reception of the flange of a ring, or a ring carrier, a portion of the rail constituting the wall of the spindle opening being resilient and relatively movable, to constitute a holding member for a ring or ring-carrier when seated.

3. In ring spinning or twisting apparatus, a ring-rail having integral therewith an annular seat surrounding the spindle opening, a segmental portion of the seat being movable relatively to the remainder of the seat, to engage and hold a ring, or a ring-carrier when mounted in the seat.

4. In ring spinning or twisting apparatus, a ring-rail provided with a spindle opening and having a concentric annular seat for the reception of the flange of a ring, or a ringcarrier, means integral with the rail to engage and hold in position a ring or ringcarrier when seated, and a clamping screw cooperating with said means.

A ring-rail provided with a spindle opening and having a concentric, annular seat adapted to receive the flange of the largest ring to be used, a segmental holding member integral with the rail and in which a part of the seat is formed, a manually adjustable clamping screw cooperating with said member, and a detachable ring-carrier having a circular edge to fit said seat and provided with means to engage and retain a ring.

6. A ring-rail having a spindle opening and provided with a concentric annular seat, a segmental portion oi such seat being outwardly movable and formed integral with the rail, the seat being adapted to receive the flange of the ring of large diameter or the peripheral portion of a ring-carrier of like diameter, and means to press the movable portion of the seat inward.

7. A ring-rail having a spindle opening and provided with a concentric annular seat, integral with the ring-rail and having a portion thereof movable toward and from the center of the opening, and means carried by the ring-rail to press inward the movable portion of the seat, the latter being adapted to receive the flange of a ring, or a circular ring-carrier.

8. In ring spinning or twisting apparatus, a ring-rail, and an annular, eXpansible seat integral therewith, and adapted to receive and hold the flange of a ring, or a circular ring-carrier.

9. In ring spinning or twisting apparatus, a ring-rail, an annular, expansible seat i11- tegral therewith and adapted to receive and hold the flange of a ring, or a circular ring carrier, and means to positively compress the seat upon the ring-flange or ring-carrier.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

ALBERT C. RHODES.
